    0.31M

    Explanation:

    Step 1:

    Data obtained from the question. This includes the following:

    Initial Volume of solution (V1) = 0.7L

    Initial concentration (C1) = 0.33M

    Final volume (V2) = 50mL + 0.7L

    Recall:

    1000mL = 1L

    50mL = 50/1000 = 0.05L

    Final volume (V2) = 0.05 + 0.7 = 0.75L

    Final concentration (C2) = ... ?

    Step 2:

    Determination of the concentration of the diluted solution.

    Using the dilution formula, the concentration of the diluted solution can be obtained as follow:

    C1V1 = C2V2

    0.33 x 0.7 = C2 x 0.75

    Divide both side by 0.75

    C2 = (0.33 x 0.7) / 0.75

    C2 = 0.31M

    Therefore, the concentration of the diluted solution is 0.31M
